| 20100297421 | Blast Energy Mitigating Composite - A blast energy mitigating composite useful for protecting a surface or an object from a blast, shock waves, or stress waves caused by a sudden, violent release of energy is described. Certain configurations of the blast energy mitigating composite may include a energy mitigating units contained in an energy mitigating matrix. The energy mitigating units may comprise a porous energy mitigating material such as carbon foam. | 11-25-2010 |
| 20100266813 | Carbon Foam and High Density Carbon Foam Composite Tooling - Tools for the forming of composite parts from composite forming materials, having tool bodies that comprise, at least in part, carbon foam and high density carbon foam are described. In some embodiments, a surface of the carbon foam or high density carbon foam may comprise a tool face. In other embodiments, the carbon foam or high density carbon foam may support an other material, referred to as tool face material, wherein a surface of the tool face material may comprise a tool face. The tools of the present invention may be lighter, more durable, and less costly to produce and/or use than conventional tools used for the production of composite parts, particularly those tools used for the production of carbon composites. Additionally, such tools may be reusable, repairable, and more readily modifiable. | 10-21-2010 |
| 20100264562 | High Density Carbon Foam Composite Tooling - Tools for the forming of composite parts from composite forming materials, having tool bodies that comprise, at least in part, high density carbon foam where a surface of the high density carbon foam may comprise a tool face or support tool face materials. The tools of the present invention may be lighter, more durable, and less costly to produce and/or use than conventional tools used for the production of composite parts, particularly those tools used for the production of carbon composites. Additionally, such tools may be reusable, repairable, and more readily modifiable. | 10-21-2010 |
| 20100263187 | Exhaust Gas Deflector and Shield - A shield for deflecting or shielding exhaust gas streams is described. The exhaust shield may comprise a shielding layer comprised of high density carbon foam. The exhaust shield may include an exhaust shield support layer affixed to the shielding layer. In some embodiments the exhaust shield support layer comprises carbon foam. If desired the exhaust shield may be comprised of more than one layer of high density carbon foam or carbon foam. The layers of carbon foam and high density carbon foam may be arranged sequentially through the thickness of the panel. The exhaust shield may be used to protect structures from exhaust gas streams such as those from engines or motors, including jet engines or rocket motors. | 10-21-2010 |
| 20100136320 | Carbon Foam and High Density Carbon Foam Assembly - An assembly comprising carbon foam and high density carbon foam is described. In some embodiments, such an assembly may be a composite or composite assembly. One or more pieces of carbon foam and high density carbon foam may comprise the assembly. The assembly may comprise other materials in addition to the carbon foam and high density carbon foam. One or more of any given type of other material may be incorporated into the composite. Additionally, a given other material may be incorporated in more than one volume or location on or in the assembly. The other materials may provide for bonding of the elements of the assembly together, strengthening of the assembly, increased assembly oxidation and weathering resistance, modification of the electrical, thermal, or fluid transport properties of the assembly, and any of a number of other purposes. | 06-03-2010 |
| 20100136292 | Carbon Foam and Graphite Composite Tooling - Tools for the forming of composite parts from composite forming materials, having tool bodies that comprise, at least in part, carbon foam and graphite are described. In some embodiments, a surface of the carbon foam or graphite may comprise at least a portion of a tool face. In other embodiments, the carbon foam or graphite may support another material, referred to as tool face material, wherein a surface of the tool face material, may comprise at least a portion of a tool face. The tools of the present invention may be lighter, more durable, and less costly to produce and/or use than conventional tools used for the production of composite parts, particularly those tools used for the production of carbon composites. Additionally, such tools may be reusable, repairable, and more readily modifiable. | 06-03-2010 |
| 20080299378 | Electrically Gradated Carbon Foam - Electrically gradated carbon foam materials that have changing or differing electrical properties through the thickness of the carbon foam material and methods for making these electrically gradated carbon foam materials are described herein. In some embodiments, the electrically gradated carbon foam materials exhibit increasing electrical resistivity through the thickness of the carbon foam material such that the electrical resistivity near a second surface of the carbon foam is at least 2 times greater than the electrical resistivity near a first surface of the carbon foam. These electrically gradated carbon foam materials may be used as radar absorbers, as well as in electromagnetic interference (EMI) shielding schemes. | 12-04-2008 |
